Definitions

  • the invention relates to socks and in particular to friction-forming socks.
  • FR 2 204 730 A1 discloses an extrusion die for making non-woven fabric which is adaptable for socks, for example.
  • the object of the invention is thus to develop a new sock for patient use and a method of manufacturing such a sock.
  • the object of the invention is achieved with a sock and method which are characterized by what is stated in the independent claims. Preferred embodiments of the invention are disclosed in the dependent claims.
  • the invention is based on the sock having a tubular mesh structure, formed of single-element monofilaments and flexible in its transverse direction, at least.
  • Benefits of the solution include the ability of the sock to breath, and a good fit to feet of different sizes, and simple manufacturability.
  • Figure 1 is a schematic view of a sock 1 for patient use.
  • Patient use may comprise the use of the sock by a patient at home care, hospital care, or care at another similar facility. Usage situations may vary, comprising bed rest, sitting, and/or moving of the patient either alone or aided. Obviously, the sock now disclosed is suitable for other purposes as well and is not restricted to the above usage situations.
  • the sock 1 for patient used comprises a tubular mesh structure 2, such as a mesh structure 2 of the type shown schematically in Figure 2 .
  • the mesh structure 2 is breathable due to its very structure and consequently it is not sweaty.
  • the mesh structure 2 is flexible at least in its transverse direction, that is, in the direction transverse in relation to the longitudinal direction of the tube.
  • the mesh structure is adaptable in a fitting way, forming to the shapes of a foot but not compressing them, for feet of different sizes and is suitable, for example, to be simultaneously used with patient clothes or means of treatment of various kinds.
  • the mesh structure 2 may be formed to be flexible in its longitudinal direction, too.
  • the mesh structure 2 comprises monofilaments 3.
  • the mesh structure 2 is formed of single-fibre, yarn-like parts.
  • the monofilaments 3 may be monolithic, that is, single-element ones.
  • the monofilaments 3 in this case do not comprise a plurality of intertwined fibres of possibly different materials, or nested or adjacent layers of materials, but consists of one fibre that is of the same uniform material through the entire cross section of the monofilament.
  • the monofilament 3 shown in Figure 2 has a round cross section, but in different embodiments the cross section of the monofilament 3 may also be oblong, square, polygon, or of another appropriate form.
  • Figures 4a-4e show cross sections of monofilaments 3.
  • Figure 4a shows a monofilament 3a of the first layer and 3b of the second layer, substantially round as to their cross section.
  • Figure 4b shows a monofilament 3a of the first layer and 3b of the second layer, substantially triangular as to their cross section.
  • the cross section of the monofilament 3 may be chosen such that is directs a massaging effect on a foot.
  • the monofilament 3 may be adapted tubular by arranging a channel 11 inside it, as in the embodiments of Figures 4c and 4d .
  • the monofilament 3 may be hollow on the inside.
  • the cross section of the filament in Figure 4d is substantially round, it is obvious for a person skilled in the art that the cross section of the monofilament may also vary in embodiments in which a channel 11 is arranged within the monofilament.
  • mesh structure 2 may comprise fibre mass.
  • the fibre mass may comprise a material in which fibres have been mixed with or into the monolithic material.
  • Fibre mass in this case does not refer to a fibre filament in which fibres have been twisted or twined to each other or, for example, adapted into substantially parallel fibre bundles, but material in which cut fibres are mixed into the rest of the material mixture.
  • Embodiments comprising fibre mass are suited to usages where it is necessary to strengthen the mesh structure against, for example, incisions by the means of treatment or other external pieces, and in which the mesh structure as such allows an adequate degree of flexibility.
  • other material may have been adapted than the material of the monofilament.
  • fibre mass for example, may be adapted.
  • the fibre mass may have been mixed into the monolithic material.
  • coated fibres, or fibres adapted inside a second monolithic material may have been adapted, as in Figure 4d . Even in such a case, it is advantageous that it is specifically the monofilaments 3a of the first layer and the monofilaments 3b of the second layer of the mesh structure 2 that are welded together on the surfaces facing each other at intersecting points 4. In other words, fibres or fibre mass possibly adapted inside the monofilament 3 form a filler and do not extend to the welding.
  • the monofilaments 3 are adapted in at least two layers so that the monofilaments 3 of each layer are adapted mutually substantially parallel and crosswise 3 in relation to the monofilament of the subsequent layer.
  • the mesh structure 2 comprises a plurality of mutually substantially parallel first-layer monofilaments 3a adapted in the first layer, and a plurality of mutually substantially parallel second-layer monofilaments 3b adapted in the second layer.
  • Each monofilament 3a of the first layer is adapted in each particular case to intersect at least one second-layer monofilament 3b.
  • the intersecting points of the monofilaments 3, 3a, 3b of two different layers form intersecting points 4.
  • Each monofilament 3, 3a, 3b intersects the monofilament of the subsequent layer in at least one intersecting point 4. Outside the intersecting points 4 both the monofilaments of the same layer and different layers may advantageously move in relation to each other, advantageously in a substantially free manner.
  • the monofilament 3, 3a, 3b may advantageously be welded to the intersecting monofilament in the subsequent layer.
  • the monofilament 3a of the first layer may, in the areas on the side of the second layer, be solidly welded together to an area of the monofilament 3b on the side of the first layer at the intersecting point 4.
  • the surfaces of at least monofilaments 3a, 3b are in such a case fused together in the intersecting area of the monofilaments 3a, 3b, facing each other,
  • the welding may advantageously be achieved by forming the mesh structure 2 by an extrusion method by means of two nozzles adapted one inside the other and rotating in opposite directions, whereby each nozzle forms the monofilaments of one layer in each particular case.
  • the mesh structure 2 may be established at one work stage without specific moulds or similar special tools, except for the nozzles, which speeds up and simplifies the manufacturing process. At the same time, coating and other work stages related to coatings and similar manufacturing methods may be avoided.
  • the sock 1 may be formed entirely as a single element one. In this case, the sock 1 does not comprise any separate material layers or material fibres connected to each other in one way or another, but is formed in its entirety out of the same material. In an embodiment, the sock 1 may be entirely formed as a mesh structure 2 formed by monofilaments. In such a case, the sock 1 does not comprise any separate parts, or parts attached to the sock, differing from the mesh structure 2 as to their structure. In an embodiment, the sock 1 may be entirely formed as a mesh structure 2 formed by single-element monofilaments.
  • the monofilament 3 is formed of a material with a high friction coefficient.
  • a high friction coefficient means that the monofilament 3 is formed of a material that has a higher friction coefficient in relation to the common floor surface materials, in other words, a higher static coefficient of friction and/or kinetic coefficient than the common sock materials such as cotton, wool, polyamide, acryl, or their combinations, typically formed as knitted fabrics of various kinds.
  • the sock 1 may in such a case act as a so-called friction sock, which may prevent a patient from slipping when he is getting onto his feet, is walking alone or aided, or when a patient is lifted.
  • the sock 1 acts as an anti-slip device without coating or other post-processing such as dip treatment.
  • the socks 1 described in this description are especially usable as friction socks also when used simultaneously with patient clothes and means of treatment of various kinds, because due to their formability they are easy to fit in feet of different sizes and, for example, over conventional patient socks or even over treatment means.
  • the mesh structure 2 may comprise thermoplastic elastomer, such as polypropylene-based thermoplastic elastomer.
  • the mesh structure 2 may comprise synthetic rubber material such as styrene butadiene rubber (SBR).
  • the mesh structure 2 may comprise monofilaments 3 comprising different two materials so that the first-layer monofilaments 3a may comprise a different material than the second-layer monofilaments 3b.
  • the monofilaments 3 of the layer against the foot in the usage position such as first-layer monofilaments 3a, may comprise a material whose friction coefficient is lower than that of the material that the second-layer monofilaments 3b comprise. In this manner, it is possible to form a sock 1 that is easy to put on the foot and which at the same time creates an efficient anti-slip effect between the foot and base.
  • Such as mesh structure 2 may advantageously be formed by the extrusion method by means of two nozzles adapted one inside the other and rotating in opposite directions, whereby each nozzle forms the monofilaments of one layer at any one time and whereby the material fed to the first nozzle 8a differs from the material fed to the second nozzle 8b.
  • the first-layer monofilaments 3a may comprise, for example, polypropylene and the second-layer monofilaments 3b may comprise, for example, polypropylene filled with EPDM rubber (Ethylene Propylene Diene Monomer rubber).
  • the inner layer may be formed of slippery and thus easy to put on and well moisture-transferring polypropylene, and the outer surface of a material that has a higher friction coefficient, and which may, however, due to the same base material may be easily adapted to weld to each other.
  • structures welding to each other comprise one or more monolithic material that have the same base substance.
  • the welding structures may in such a case comprise the same material or alternatively materials that differ from each other, but which, however, advantageously have the same matrix whereby they weld together but may nevertheless achieve different properties on different surfaces.
  • the mesh structure 2 may comprise two monofilaments 3a, 3b having different cross sections so that the first-layer monofilaments 3a may comprise a cross section of a different shape than the second-layer monofilaments 3b.
  • the monofilaments 3 of the layer against the foot in the usage position such as first-layer monofilaments 3a, may comprise a cross section whose friction coefficient is lower than the cross section that the second-layer monofilaments 3b comprise.
  • Figure 4e An example of such an embodiment is shown in Figure 4e .
  • the shape of the surface of the first-layer monofilaments 3a towards the foot in the usage position may be formed smooth and/or narrow, such as rounded.
  • the shape of the surface of the second-layer monofilaments 3b towards the base in the usage position may be formed to add to the friction and/or friction surface, such as grooved and/or wider than the surface of the first-layer monofilaments 3a, directed towards the foot.
  • Such as mesh structure 2 may advantageously be formed by the extrusion method by means of two nozzles adapted one inside the other and rotating in opposite directions, whereby each nozzle forms the monofilaments of one layer at any one time and whereby the cross section of openings 10 formed in the first nozzle 8a differs from the cross section of openings 10 formed in the second nozzle 8b.
  • the sock 1 may comprise silver ions to establish an anti-bacteria effect. So, in this case the sock 1 may be formed anti-bacterial. This is beneficial in connection with wounds and ulcers of various kinds and in hospital and similar facility environments, in particular.
  • the sock 1 may also be formed as one removing body odour.
  • the tubular mesh structure 2 is formed to be closed at one end so that the sock forms a bag-like mesh structure.
  • a sock 1 may be formed, for example, by forming a tubular mesh structure 2 by the extrusion method with two nozzles adapted one inside the other and rotating in opposite directions, and by closing one end of the tubular mesh structure 2 by melting or welding, for example.
  • Figures 3a and 3b are schematic views of socks 1 for patient use.
  • the sock 1 may comprise at least one slide block 5.
  • the slide block 5 is formed of a material having a friction coefficient lower than the friction coefficient of the mesh structure 2.
  • the sock 1 may be formed on a chosen area, that is, in the area of the slide block 5, to be better sliding than elsewhere in the area of the sock 1, such as the area of the mesh structure 2.
  • the slide block 5 may comprise a film-like or mesh-like piece.
  • one slide block 5 or a plurality of slides 5 may be fixedly adapted in the mesh structure 2 by welding.
  • one slide block 5 or a plurality of slides 5 may be adapted in the mesh structure 2 by seaming.
  • one slide block 5 or a plurality of slides 5 may be adapted in the mesh structure 2 by laminating.
  • at least one slide block 5 may be adapted in the mesh structure immovably and non-detachably by, for example, welding, seaming, or laminating.
  • At least one slide block 5 may be adapted in the sock 1 so that the slide block 5 places itself under the front part of the foot when the sock 1 has been put on a leg 6.
  • the mesh structure 2 may be formed closed at one of its ends, and the slide block 5 in such a case may be adapted in the mesh structure 2 closer to the closed end 7 of the mesh structure 2 than its open end, whereby the slide block 5 places itself under the front part of the foot when the sock has been put on the leg 6.
  • At least one slide block 5 may be adapted in the sock 1 so that it extends substantially around the sock, advantageously in the area that places itself under the front part of the foot when the sock 1 has been put on the leg 6, such as in the embodiment of Figure 3b .
  • the advantage of such a sock 1 is that it does not matter which way or in which position the sock is put on the leg.
  • the sock 1 comprises two slides 5.
  • the sock 1 may comprise, as stated in the above, just one slide block 5, such as the slide block 5 of Figure 3a , arranged on the left, so in connection with the closed end of the sock 1, in other words under the front part of the foot.
  • a second slide block 5 may be adaptable to be placed under the heel according to Figure 3a .
  • the slide block arranged under the heel may, for example, in an embodiment comprise material that has a higher friction coefficient that the slide block 5 adaptable under the front part of the foot.
  • the sock 1 comprises a separate flexible cuff.
  • the flexible cuff may be formed of the same material as the mesh structure 2 or of a different material. Such a flexible cuff may facilitate putting on the sock 1 and helps the sock stay on the leg.
  • the flexible cuff may be fixedly adapted in the open end of the mesh structure by welding, for example.
  • FIG 5 is a schematic representation of a method for making a sock 1 for patient use, such as any of the socks 1 disclosed in this description.
